 number of 'The Auk' the note by Mr. Reginald Heber Howe. Jr. on a 

 certain imprint of this work reminds me that I have a copy with similar 

 imprint in my ornithological library. My copy has untrimmed margins, 

 is yellow with age and bound in cardboard covered with a thin, unmarked, 

 uncolored cloth. This copy contains 528 pages, 506 being of text, fol- 

 lowed by an Index, Prospectus, Contents of Vol. I of the Birds of Amer- 

 ica, Extracts from Reviews, and List of Subscribers. My copy was 

 received in 1S94 from Wm. D. Doan of Coatsville, Pa.— W. E. Snyder,

Cooke's Distribution and Migration of North American Warblers. 1 — 

 It is with great pleasure that we welcome Professor Cooke's important 

 contribution to our knowledge of the seasonal distribution and migration 

 of this, one of the largest and the most distinctly peculiar of North 

 American birds, the Warblers, or the Mniotiltidae. It is a subject which 

 has long occupied the author's attention, and for the investigation of 

 which he has had access to an accumulation of data gathered during 

 many years of well directed effort on the part of the Chief of the Bio- 

 logical Survey, Dr. C. Hart Merriam — an amount of information 

 unequalled outside of North America for the investigation of the distri- 

 bution and migration of the birds of any area or of any group. The 

 degree of migration exhibited by different members of the family varies, 

 as is well known, from nearly sedentary species to those which breed as 

 far north as the limit of arboreal vegetation and spend the winter far 

 dovvn in the tropics. Some, also, are exceedingly local in their disper- 

 sal, while others range over a large part of two continents. 



Professor Cooke treats first and rather briefly (pp. 8-14) of migration 

 routes, on the same lines as in his paper in the present number of 'The 

 Auk' (pp. 1-15) entitled 'Routes of Bird Migration,' and also in his 'Some 

 New Facts about Bird Migration' (see Auk, XXI, p. 501), but of course 

 with more direct reference to his present subject. The species are first 

 (pp. 14-16) briefly reviewed with reference to the " southernmost exten- 

 sion of their winter ranges," those of eastern North America being
